1. 2:97Al-Baqarah
   قُلۡ مَن كَانَ عَدُوّٗا لِّـجِبۡرِيلَ فَإِنَّهُۥ نَزَّلَهُۥ عَلَىٰ قَلۡبِكَ بِإِذۡنِ ٱللَّهِ مُصَدِّقٗا لِّمَا بَيۡنَ يَدَيۡهِ وَهُدٗى وَبُشۡرَىٰ لِلۡمُؤۡمِنِينَ
   Say (O Muhammad, to mankind): Who is an enemy to Gabriel! For he it is who hath revealed (this Scripture) to thy heart by Allah's leave, confirming that which was (revealed) before it, and a guidance and glad tidings to believers;
   In context

   Say, O Muhammad, to those of the Jews who say that Gabriel is their enemy among the angels, that whoever is against Gabriel – who revealed the Qur’ān to your heart, with Allah’s permission, affirming the sacred scripture that came before it, such as the Torah and the Gospel, showing the way to what is good, and bringing the good news to the believers of the bliss Allah has prepared for them – then…

2. 2:98Al-Baqarah
   مَن كَانَ عَدُوّٗا لِّلَّهِ وَمَلَـٰٓئِكَتِهِۦ وَرُسُلِهِۦ وَجِبۡرِيلَ وَمِيكَىٰلَ فَإِنَّ ٱللَّهَ عَدُوّٞ لِّلۡكَٰفِرِينَ
   Who is an enemy to Allah, and His angels and His messengers, and Gabriel and Michael! Then, lo! Allah (Himself) is an enemy to the disbelievers.
   In context

   Whoever stands against Allah, His angels and His prophets, and against His two angels Gabriel and Michael, then certainly Allah is a rival to the disbelievers from among you, and from other than you. Certain defeat faces whoever has Allah as his rival.

3. 66:4At-Tahrim
   إِن تَتُوبَآ إِلَى ٱللَّهِ فَقَدۡ صَغَتۡ قُلُوبُكُمَاۖ وَإِن تَظَٰهَرَا عَلَيۡهِ فَإِنَّ ٱللَّهَ هُوَ مَوۡلَىٰهُ وَجِبۡرِيلُ وَصَٰلِحُ ٱلۡمُؤۡمِنِينَۖ وَٱلۡمَلَـٰٓئِكَةُ بَعۡدَ ذَٰلِكَ ظَهِيرٌ
   If ye twain turn unto Allah repentant, (ye have cause to do so) for your hearts desired (the ban); and if ye aid one another against him (Muhammad) then lo! Allah, even He, is his Protecting Friend, and Gabriel and the righteous among the believers; and furthermore the angels are his helpers.
   In context

   It is your duty that you both repent, because your hearts have inclined towards liking something the Messenger of Allah (peace be upon him) disliked, i.e. staying away from his servant girl and forbidding her upon himself. And if you insist upon joining forces against him, then know that Allah is his guardian and helper, and so is Gabriel and the best of believers.
